A commonly seen bite mark susceptibility artifact in the inferolateral and anteroseptal myocardial wall in cardiac cine SSFP images can degrade morphologic and functional evaluation, particularly for R2* mapping. Two explanations have been previously proposed, that these artifacts originate from 1) the heart-lung interface or 2) deoxygenated blood in adjacent cardiac veins. The purpose of this study was to determine whether the geometry of the heart-lung interface alone accounts for "bite mark" artifacts in vivo.
